TECHNICAL FEATURES
terminals 1 - 2 and closes 1 - 4
1 - WALL MOUNTING
Intellitherm C76 is supplied complete with a base
suitable for mounting flush in a rectangular three-
module or a round outlet box, or for attaching to the
wall.
Fit the controller 1.5 m above floor level, well away
from kitchens, sources of heat, doors or windows.
Make sure that the base is attached on a level and
without any straining.
2 - ELECTRICAL CONNECTIONS
Connect terminals 1 - 2 to the heating system with two
wires, replacing the conventional thermostat at any
time, without adding any further connections. When
the room temperature increases, the relay opens
.
Terminal 4 is free and can be used for signals or other
purposes.
3 - “OFF MODE” SELECTION
During periods when it is OFF, Intellitherm can be set
to maintain a temperature setting of 5°C to protect the
system from the risk of freezing.
If you require such ANTIFREEZE protection, position
the dip switch (situated at the bottom left-hand side on
the back of the body of the C76) on HIGH. If, on the
other hand, you want the system to be switched OFF
completely, position the dip switch on
LOW
.
This selection must be made at the time of installation
and before fitting the batteries.
NOTE: if, at any time after installation, you wish to
change this selection, the Intellitherm must be
reset and reprogrammed.
4 - FITTING THE C76-C76B BODY ON THE BASE
5 - FITTING THE BATTERIES
Insert two good-quality, alkaline long-life AA 1.5 V
pencil batteries in the space provided, taking care to
comply with the polarity indicated. The batteries can
last about two years; when they begin to run down,
the battery symbol on the display starts to flash .
If the batteries are not changed within 15 days,
Intellitherm
C76
will automatically switch off and only
the word OFF will appear on the display.

With Intellitherm C76, you can keep a check on how many
hours the heating has actually been on (relay closed - ON)
on
the previous day or since the temperature controller was last
enabled (i.e. since the last time the batteries were changed
or
the device was reset).
Move the switch S to the (economy) position
for the MINIMUM temperature or to the
(Comfort)
position
for
the MAXIMUM

When you move the switch I to the SUMMER position, Intellitherm C76
switches to operating the AIR CONDITIONING system. The red knob is used for
adjusting the comfort mode temperature required in the room, while the economy
and antifreeze modes are disabled.
The red sectors on the ring appearing on the display consequently indicate the
hours when the air-conditioning system is in operation, while the sectors in any
other color indicate when it is off.
With Intellitherm C76 you can also keep a check on
the MINIMUM and MAXIMUM temperatures
recorded in the room on the previous day and the time
when they occurred.
